Consider the turbocharger of an internal combustion engine. The exhaust
gases enter the turbine at 450 °C at a rate of 0.02 kg/s and leave at 400 °C. Air
enters the compressor at 70 °C and 95 kPa at a rate of 0.018 kg/s and leaves
at 135 kPa. The mechanical efficiency between the turbine and the
compressor is 95 percent (5 percent of turbine work is lost during its
transmission to the compressor). Using air properties for the exhaust gases,
determine (a) the air temperature at the compressor exit and (b) the isentropic
efficiency of the compressor.
